4 Claims.

This invention relates to improvements in containers.

The main objects of this invention are:

First, to provide a covered container which may 5 be formed of quite light material and at the same .time has suficient strength for many purposes, also one on which a telescoping cover may be quickly applied.

Second, to provide a fibrous walled paper container with a telescoping cover.

Ob-jects pertaining to details and economies of the invention will appear from the description to follow. The invention is dened in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings in which:

Fig. 1 is a plan view of the side Wall blank of my improved container and illustrating one of the steps in forming the same.

Fig. 2 is a'perspective view illustrating a second step in forming the container wall.

Figs. 3 and 4 are fragmentary sectional views illustrating succeeding steps in the manufacture of the container.

Fig. 5 is an enlarged fragmentary sectional view showing the bottom structure of the container.

Fig. 6 is a fragmentary sectional View illustrating a further step in the manufacture, name- 1y, that of formingl a cylindrical rim portion on Va fibrous side wall.

Fig. '1 is an inverted perspective View of the container after the side wall has been formed to provide a cylindrical rim portion thereon.

Fig. 8` is a perspective View of a spirally wound tube of fibrous material from which the rim collars are cut.

Fig. 9 is a fragmentary view partially in section illustrating the cutting and forming of the collar.

Fig.A 10 is an inverted .perspective view of the formed rim collar.

Fig. 11 is a fragmentary view partially in Vertical'section of the completed container, the container being shown in inverted position.

Y Fig. 12 is a. side 'elevation of a stack of the container bodies. f

Fig. 13 is a fragmentary vertical section of the container with. its cover thereon. y,

Referring to the drawings I represents a lsheet of fibrous material such as container stock which is cut into a segmental form and this is rolled into the side wall 2 shown at Fig. 2 with the edges 3 and 4 overlappingfthe edges being adhesively secured together. This formed wall is then placed in a forming die 5 and the plunger 6 (Cl. 22S-5.5)

thereof actuated to form an inturned flange 1 at the bottom. The bottom isthen secured in place. The bottom consists of an inner member 8 and an outer member 9 overlapping the top and bottom of the annular flange 1 and adhesively secured E thereto and to each other, the adhesive being indicated at III. This `provides an eective rigid bottom of fibrous material. However, the bottom may be formed of other material and other` wise attached. 10

The next step subjects the wall to coacting forming dies II and I2, see Fig. 6, thereby forming a cylindrical rim portion I3 on the side walls of the-container and having a downwardly facing 'curved shoulder I4 at'the lower edge thereof. 15

This rim portion I3 is reinforced by the collar I5 of fibrous material, this collar having an inturned curved flange I6 at its lower edge and being fixedly secured throughout to the rim portion I3, preferably adhesively. The collar I5 is endless 20 and is preferably formed by cutting a section of the proper width from a spirally wound tube I1 of proper dimensions. 'Ihe section may be cut oi by a rotary cutter I8 coacting with a suitable mandrel I9. At the same time the flange I6 25 may be formed as by means of the suitably shaped roller 20.

With the endless collar I5 sleeved upon and xedly secured to the rim portion I3 of the container side wall, I provide a rim which is quite 30 stiff and resistant to collapsing and one with which a cover as indicated generally by the numeral 2| may be telescoped. This cover illustrated comprises a flange portion 22 having inner and outer walls 23 and 24 seamed into the in- 35' turned portions 25 at the upper edge of the flange. This provides a cover of considerable rigidity, even when formed of comparatively light material and one which can be slipped upon the container.l and may be made a close fit with its cylin- 40 drical rim portion so that the container is not only effectively sealed or closed but may be repeatedly opened and closed. My improved container may be very economically produced and is suitable for merchandising various products. 45 It has the advantage of a cylindrical container so far as a telescoping cover is concerned, and has the further advantage of tapered containers in5that the'containers may be nested for shipment and storage.

I have illustratedand described my improvements in an embodiment which I consider very practical. I have not attempted to illustrate* other adaptations as it is believed this disclosure 55 will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is: Y v

1. A container comprising a tapered side wall of brous material having its upper end conformed to provide a cylindrical rim portion ter-v minating at its lower edge in a downwardly facing shoulder, and a cylindrical collar formed of a section of spirally woun'd tubing of fibrous material closely tting said cylindrical rim portion of said container wall and having a flange at its lower edge tting over said shoulder, said collar being adhesively secured to said side wall rim portion and coacting therewith to provide a rein-` minating in a downwardly facing shoulder, an

endless cylindrical collar of brous material having an intm'ned'ange at its lower edge embracr ing said rim portion of said wall with its flange overlapping said shoulder, said collar being adhesively secured to said side wall, and a cover comprising a ilange of mbrous material telescopingly engageable with said rim portion of said container. 1

, 3. A container comprising a tapered brous side wall, the upper end ofthe side wall being conformed to provide a cylindrical rim portion -terminating in a downwardly facing shoulder,

and a cylindrical collar of fibrous material having an inturned flange at its lower edge embracing said rim portion of said wall with its ange 4overlapping said/shoulder, said collar being adjhesively secured to said side wall rim portion and coacting therewith to provide a reinforced rim for the container with which a cover may be telescoping'ly engaged.

4. A container c omprising a tapered iibrous side wall formed of a strip having overlapping,

edges, the upper end of the side wall being conformed to provide a'cylindrical rim portion terminating in a downwardly facing shoulder, and

' a cylindrical collar formed of a section of spirally ROBERT E. RU'ILEDGE.
